I got my computer as a birthday present and I mainly use it to play games, I don't mind played with lower settings to get a decent fps however playing things like gta are almost impossible with bugs and breakages so often. This is most likely down to the fact I have an apu and no gpu. However I don't know a thing about mother boards and am not sure what graphics card could fit which slot or whatever as well as there being 3 different slots. I have an Asus F2A55-M LK2 motherboard. Im not sure whether it would be worth investing in a new motherboard as well or not dependant on how big the improvement would be with the graphics card
